This feature does not add any extra effectiveness to the machine. But a 4-stroke one adds oil to the moving parts and this increases the lifespan of the engine.

2) Weight: Buying lightweight gas weed eaters will save you time and provide comfort.

3) Cutting Width: Blades with higher cutting width will help you work faster. It’s a bonus if the blades are expandable and adjustable.

4) Shaft type: You have to choose ​a weed eaters compatible to your height. If you are tall, you can choose models with a long shaft. This way, you can then easily reach areas where you would have to bend over otherwise.
Curved shaft weed eaters work in a perfect way by while cleaning areas where you can hardly reach. This requires minimal force and effort.
Getting under bushes is difficult with curved shafts while easier with straight shafts. Straight shafts easily clean areas under bushes and corners.
